METAL BEDSTEAD.

Specification of Letters Patent.

Application filed August 6, 1913. Serial No. 783,264.

To (ZZZ whom it may concern.

Be it known that 1, MAX DUNNER, a cit-izen of the United States, and aresidentof ih'ooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Metal Bedsteads, ofwhich the following is a specification.

The invention pertains more particularly to a novel construction of thecorners of the upper ends of the end frames of metal bedsteads wherebythe upper end of said end frames may be formed of rectangular tubing andhave its end portions properly bent downwardly at right angles to jointhe corner posts of the end frames. It is desirable in many instancesthat the corner posts and transverse rails of the end frames of metalbedsteads be of rectangular formation in cross-section, and greatdifliculty has eX- isted in so shaping the ends of the upper transversebars of the end frames as to present a desirable appearance. It isextremely diflicult to bend a piece of rectangular tubing on curvedlines, and especially so in attempting to bend the ends of the tub ingon the short curves that are required for the upper corners of endframes of metal bedsteads of customary size.

The object of my invention is to provide a construction whereby the endsof a piece of tubing, rectangular in cross-section, may be bentdownwardly on graceful curved lines and thereafter be used as the toprail or member of the end frame, either head or foot, of a metalbedstead, the piece of tubing having its ends thus bent downwardly beingadapted for connection with the usual corner posts for the bedstead,said corner posts also being rectangular in cross-section andcorresponding in diameter with the said top rail or upper member.

In carrying out my invention I form the top member or upper rail of theframe from a sheet of metal and cutout the same at its end portions in aspecial manner to constitute the whole sheet as a blank from which thesaid upper member and downwardly extended outer portions are to beformed, and. said invention will be fully understood from the detaileddescription hereinafter pre sented, reference being had to theaccompanying drawing, in which:

Figure 1 is an elevation of the end frame of a metal bedstead embodyingmy invention, the same being shown on a small scale; Flg. 2 1s a topview of the blank, also shown on a small scale, from which the upper memher or top rail of the end frame and the corners thereof are formed;Fig. 3 is a perspectlve view of one portion of the upper member or railof the end frame as formed from the blank shown in Fig. 2 but in thestage it presents prior to the end portion of the tubular member beingbent downwardly to form the corner of the said end frame; Fig. 1 is acorresponding perspective View of one end portion of the upper rail ortubn lar member after the end portion thereof has been bent downwardlyin the formation of a corner of the end frame; Fig. 5 is a \erticalsection through a portion of the upper member or rail of the end frameafter the latter has reached its completed condition, the section beingon the dotted line 5--5 of Fig. 7 Fig. 6 is a horizontal sectionthrougl'i a portion of the completed upper member or rail of the endframe taken 011 the dotted line 66 of Fig. 7, and Fig. 7 is a verticalsection through a portion of the upper ail or member taken on the dottedline 77 of Fig. 6.

In the drawings, 10 designates the end frame, either head or foot, of ametal bedstead, which with the exception of the pres ence of myinvent-ion in the upper member or ail 11 thereof, of customaryconstruction, the corner posts being designated by the numeral 152 andthe sockets for receiving the side rails of the bed by the numeral 13.The upper member or rail 11 is rectangular in cross-section and isconnected with the corner posts 12 by means of castings, commonly calledchills, 14. My invention resides wholly in the formation of the uppermember or rail 11, and particularly in the coin struction of the endportions of said membcr whereby downwardly extending ends 15 may beformed thereon to match the upper ends of the corner posts 12 and beconnected therewith by the chills 1d.

The upper member 11 of the end frame is formed from a sheet metai blank16 shown in detail in Fig. 2, said blank in carrying out my inventionbeing bent to constitute the transverse bar 17 and the said dowiiiwardlyextending ends 15. :l indicate by dotted lines in Fig. 9 the lines onwhich the blank 16 is to be folded to create the rectangular PatentedOct. 28, 1913.

member 11. shown in Fig. a, which has an outer face 18, an inner face19, and two side faces 20, 21. The dotted lines 22, in Fig. 2, definethe panel from which the outer face of the bed member 11 is formed, andsaid dotted line with the dotted line 2st de lines the panel for theside 20 of the bed member 11, while said dotted line 2a and the dottedline 25 define the panel for the inner face 19 of said bed member 11,and the dotted line 22 with the dotted line 26 defines the panel fromwhich the other side 21 of the bed member 11 is formed. The dotted lines22, 23, 2 1, 25 and 26, while bro-ken at the spaces cut in the blank adja cent to the ends thereof, extend to the extreme ends of the blank,except at such cutaway portions, and therefore the outer and inner andside panels of the bed member 11 are present finally in not only thetrans verse horizontal bar 17 but in the end portions 15 of said bar.Outwardly from the dotted line 25 and between said line and the extremeadjacent edge of the blank 16, the metal is bent inwardly, as at 27, toform a flange extending lengthwise of one edge of the inner panel 19 ofthe bed member 11, and between the dotted line 26 and the eX- tremeadjacent edge of the blank 16 th metal of the blank 16 is bent inwardlyon the dotted line 28 and then outwardly to form a pocket extendinglengthwise of the bed member 11 to receive the aforesaid flange 27, asshown in Figs. 3 and 5, the pocket 29 being disposed within the outlineof the bed member 11. so as not to disfigure the same and in usecooperating with the flange 27 to lock the blank in its rectangularformation. I preferably apply solder to the joint between the flange 27and pocket 29 so that even with rough usage there may be no danger ofthe seam in the adjacent edges of the bed member 11 formed from theblank 16 opening. The turning inwardly of the flange 27 and pocket 29leaves the face 21 of the bed member 11 substantially smooth and uniformthroughout.

Those portions of the panels of the blank 16 to constitute the sides 20,21 of the bed member 11 are cut out as at 30 and 31, at the points whichin the transformation of the blank into the bed member 11 willconstitute the corner portions of said bed member. The recessing of theblank 16 at 30, 31 is special in that thereby are formed between thedotted lines 23, 2st corresponding facing somewhat triangularly-shapedsections 32 having straight edges on one side and curved edges on theother side, and that thereby are also formed similar sections 33 betweenthe dotted line 22 and the adjacent outer edge of the blank 16. Thatportion of the blank 16 between the dotted lines 22, 23 extendscontinuously from one end to the other of the blank, and between thereecsses 30, 31 formed in the blank there is created in said part of theblank between the dotted lines 22, 23 sections 3st which are free to bebent over and downwardly, as at (Figs. 4 and 7) to form the outercorners the bed member 11, the sections being a single piece and flatand adapted to be readily bent on curved lines to create such corners,and it will be seen, on reference to the drawings, that when thesections 3 1 are bent downwardly, as at 35, to form the outer corners ofthe bed member 11, the curved edges of the sections 32, 33 fit snuglybelow the outer edges of such corners, while the other or mitered edgesof said sections 32, 33 come together along the line 36 (Fig. 4) andmake a proper finish for the side faces of the bed member 11. Thesections 3% of the blank 10 are bent over on curved lines, and thecurved edges of the sections 32, 33, by fitting within the edges of thesaid sections 34: when the latter are bent downvardly, serve tostrengthen the outer corner portions of the bed member 11 and impart tothe article that strength which the upper portion of a head-frame orfoot-frame ought to have.

That portion of the blank 16 between the dotted lines 2%, 25 instead ofbeing continuous to correspond with that portion of the blank betweenthe dotted lines 22, 23, is slit transversely, as at 37, in line withthe trans verse center of the recesses 31 to form lips 38 which, in theformation of the bed member 11, may be bent inwardly on the jointline 36between the sections 32, 33 and soldered together as in Fig. 7 toadditionally secure a rigid formation in the end portions of the bedmember 11. In carrying out the invention 1 not only solder the lips 38together at each corner of the bed member 11, but also solder the curvededges of the sections 32, 33 to the outer panel of said bed member, sothat finally my structure is a very secure and rigid one, capable ofwithstanding considerable rough usage. After the blank 16 has beenfolded to form the straight construction shown in Fig. 3, the lips 36,36 are bent inwardly on corresponding lines for the end portions, andthe rectangular structure shown in Fig. 3 is bent downwardly on linesextending transversely of the sections 3% of said blank, thus, with theexception of the proper soldering, completing the entire bed member 11,ready for application to the other portions of the head or foot frame ofa bedstead. The bed member 11 produced in accordance with my inventionis rectangular in cross-section, of very rigid and durable structure, ofuniform cross-section across its transverse bar portion 17 and verticalend portions 15, has a nicely curved outer surface at each corner and atthe inner surface of said corners has a definite right-angularformation. The

bed member when completed will be applied to the corner posts 12 bychills or castings 14.

What I claim as my invention and desire to secure by Letters-Patent, is:

An upper tubular member, rectangular in cross-section, for end frames ofmetal bedsteads comprising a horizontal transverse portion and verticalend portions integral therewith for connection with the corner posts ofsaid frames, the outer wall of said member being uniform throughout andat the corners thereof on curved lines and the inner wall of said memberat its inner corners being on right-angular lines, and the adjacent endsof the sides of said horizontal and vertical portions of said memberconstituting corresponding projections having outer curved edges fittingsaid curved corners and inner straight edges engaging each otherdiagonally at the corners of said bed member.
